New facilities are being designed and built\, while many ageing research reactors are threatened with closure. The result will be a more dynamic ecosystem of neutron facilities\, ranging from high-end facilities such as the as-yet unfinished European Spallation Source and the developm ent of its eventual successor\, to the population of an intermediate niche of modern research reactors and accelerator-based sources\, as well as tr uly compact neutron sources within the budgetary scope of a university gro up. \n\nInstrument concepts and technologies have matured greatly over the last ten years\, based on the acceptance of the need to make the most of the inherently limited neutron source brightnesses achievable. Even withou t assuming new game-changing technologies\, many trends can be identified which will lead to order-of-magnitude improvements in performance. \n\nThe re are also a number of scientific trends from which we can reasonably ext rapolate instrument design drivers: being able to design materials based o n microscopic understanding of their properties\, exploring new regimes of extreme conditions such as pressure or magnetic field\, understanding the function of biologically active molecules\, tying together structure and behaviour over multiple length and time scales. Neutron instrumentation wi ll need to adapt to address these problems\, which are all needed for addr essing the current and\, presumably\, future societal grand challenges.\n\ nhttps://events01.synchrotron.org.au/event/50/contributions/1110/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1110/ END:VEVENT BEGIN:VEVENT SUMMARY:Sample Environment Equipment for use on Neutron Instruments DTSTART;VALUE=DATE-TIME:20171129T071000Z DTEND;VALUE=DATE-TIME:20171129T071600Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1108@events01.synchrotron.org.au DESCRIPTION:Speakers: Stan Lee (Australian Nuclear Science Technology Orga nisation)\nIn order to complete and complement the neutron instruments\, A ustralian Centre for Neutron Scattering procures and commissions a continu ously evolving suite of sample environment equipment\, able to determine a nd manipulate the physical conditions under which a neutron scattering exp eriment is performed. The sample environment equipment\, therefore\, plays a crucial role in the success of an experiment\; the very role of sample environment has shifted from purely technical infrastructure to an invalua ble component of the experimental procedure. The range of equipment availa ble spans from cryostats and cryofurnaces\, superconductive magnets\, high temperature\, high pressure\, gas and vapour delivery systems to more spe cialised equipment tailored to specific necessities. \n\nIn designing a ne utron instrument\, consideration is given to ensuring the different sample environment equipment can be repeatedly and efficiently mounted\, install ed and operated within the confines of the instrument’s sample stage and surrounding floor space. Current development projects include the design \, construction and commissioning of a new superconducting split-coil magn et\, a fast cooling closed cycle cryostat and a closed cycle dilution refr igerator of the latest generation. Also in the pipeline are thermalised sa mple tumblers for SANS and USANS.\n\nhttps://events01.synchrotron.org.au/e vent/50/contributions/1108/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1108/ END:VEVENT BEGIN:VEVENT SUMMARY:Present Status of University-owned Neutron Beam Instruments at JRR -3 DTSTART;VALUE=DATE-TIME:20171201T024000Z DTEND;VALUE=DATE-TIME:20171201T030000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1107@events01.synchrotron.org.au DESCRIPTION:Speakers: Daichi Kawana (Neutron Science Laboratory\, Institut e for Solid State Physics\, the University of Tokyo)\nISSP owns 14 neutron -beam instruments in the Japan Research Reactor No. 3 (JRR-3)\, which has been built and owned by Japan Atomic Energy Agency (JAEA)\, and operates a general user-program for neutron scattering research for half a century. Unfortunately\, the operation of JRR-3 has been suspended since the Great East-Japan Earthquake disaster on Mar. 11\, 2011. To restore the JRR-3 o peration\, many tasks of safety management must be met the government regu lation. We have been proceeding mainly two following tasks in a recent fe w years.\nOne is cleaning up and rearrangement of a radiation-controlled l aboratory in JRR-3. Users-owned items were returned to the owners\, and l ess-frequently-used accessories were moved to outside of the laboratory. All the items continuously-preserved in JRR-3 have been registered in a da tabase with the owner\, installation location\, period and specific charac ter are recorded.\nThe other is an organization of an inter-facility safet y-and-health control team. In order to transfer information from the faci lity owner\, JAEA\, to the instrument staff members\, we organized “Univ ersity-owned instruments Safety-management Team (UST)” which is comprise d of one professor and technical staff members. Under the leadership of J AEA\, the UST have cooperatively proceeded comprehensive safety activities such as check of electric equipment and item management. For our instrum ents\, commissioning has been carried out together with the responsible in strument staff members\, toward the upcoming restoration of the reactor op eration.\n\nhttps://events01.synchrotron.org.au/event/50/contributions/110 7/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1107/ END:VEVENT BEGIN:VEVENT SUMMARY:How 50 years with HIFAR shaped the Australian Centre for Neutron S cattering DTSTART;VALUE=DATE-TIME:20171128T220000Z DTEND;VALUE=DATE-TIME:20171128T222000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1106@events01.synchrotron.org.au DESCRIPTION:Speakers: Margaret Elcombe (ACNS)\nThis talk will be based on my experience with Triple Axis Spectrometers over 50 years. The good and n ot so good features have had a profound influence on the changes made to t he early instruments and the design of new instruments which have occurred over the years. In the early days Australians were very good at adapting existing equipment\, writing ingenious computer algorithms and initiating the development of new materials. Later we took on designs\, materials and new technologies from overseas and incorporated into them more rigorous r adiation and safety standards to avoid many of the early pitfalls. What we learnt from this upgrade affected how and what we took forward into the d esign of both the reactor and the suite of neuron beam instruments which i s the Australian Centre of Neutron Scattering today.\n\nhttps://events01.s ynchrotron.org.au/event/50/contributions/1106/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1106/ END:VEVENT BEGIN:VEVENT SUMMARY:Detector bank upgrade of the Necsa neutron powder diffractometer DTSTART;VALUE=DATE-TIME:20171129T032000Z DTEND;VALUE=DATE-TIME:20171129T034000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1105@events01.synchrotron.org.au DESCRIPTION:Speakers: Deon Marais (The South African Nuclear Energy Corpor ation (Necsa) SOC Limited)\nThe current detector system of Necsa’s Powde r Instrument for Transition in Structure Investigations (PITSI) neutron di ffractometer consists of 15 vertically stacked 609.6 mm x 25.4 mm Reuter-S tokes He3 gas-filled position sensitive tube detectors. This assembly resu lts in a pseudo area detector with an active area of ~610 x 380 mm2. At a sample-to-detector distance of 1.6 m\, the detector spans a 2θ angle of a mere 21°\, requiring the detector to be step-scanned to 6 positions in o rder to cover a range of 10° ≤ 2θ ≤ 120°. This significantly influe nces measurement time.\n\nA project is currently under way to increase the active area of the detector by adding an additional 33 tubes. The resulti ng detector assembly will consist of three banks each containing 16 tubes\ , separated by a dead-space of 18.5° at 1.6 m. This configuration require s a step-scan of only 2 positions to cover the complete 2θ range\, effect ively increasing the instrument acquisition speed by a factor greater than 3. The sample to detector distance can be varied from 1.6 m to 1.2 m prov iding the ability to reduce the measurement time even more with a trade-of f in angular resolution.\n\nThe current USB-communication based electronic s (from Instrumentation Associates) will also be replaced by an Ethernet b ased Mesytec system to increase stability and reduce the amount of cabling needed.\n\nhttps://events01.synchrotron.org.au/event/50/contributions/110 5/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1105/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutron Chopper Vibration Analysis DTSTART;VALUE=DATE-TIME:20171129T064000Z DTEND;VALUE=DATE-TIME:20171129T064600Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1104@events01.synchrotron.org.au DESCRIPTION:Speakers: Sebastian Williams (ANSTO)\nThe backscattering instr ument managed by ANSTO called Emu was built with two neutron choppers. The se choppers condition the neutron beam and typically spin at 2400rpm and 1 200rpm respectively. They were supplied with an integrated vibration monit oring system. From late 2016\, this system would occasionally trip\, decre asing the availability of the instrument. This issue\, coupled with the de licate nature of the equipment\, created the need to better understand the sources of vibration.\n\nThrough research\, testing and consultation with the manufacturer and third-party vendors\, the integrated vibration monit oring system was found to be effective at protecting the choppers. However \, by design\, it lacked the ability to perform the detailed analysis requ ired to determine the sources of vibration\, without impacting the instrum ent’s operation. As a result\, a second independent vibration monitorin g system was installed on one of the choppers\, allowing detailed analysis .\n\nThe frequency spectrum revealed that most of the vibration experience d by the chopper was at 400Hz. Defects on bearings create vibration at kno wn frequencies\, proportional to the running speed of the chopper. These d amage frequencies can be calculated based on the geometry of the bearing. The 400Hz signal matches the 4th harmonic of the ball bearing damage frequ ency. The spectrum was observed while the chopper was slowing down and the spectral spike decreased in frequency. This was further evidence that thi s 400hz spike was due to bearing damage. \n\nIt was through this independe nt system that in-depth analysis could be completed and that the bearing d amage could be identified.\n\nhttps://events01.synchrotron.org.au/event/50 /contributions/1104/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1104/ END:VEVENT BEGIN:VEVENT SUMMARY:Motion Control Future at the STFC ISIS Facility DTSTART;VALUE=DATE-TIME:20171129T223000Z DTEND;VALUE=DATE-TIME:20171129T225000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1103@events01.synchrotron.org.au DESCRIPTION:Speakers: Stephen Cox (STFC ISIS)\nThis presentation will give an overview of the future direction for motion control at the STFC ISIS f acility. The current Galil controller based standard control system has be en used for over 10 years and was installed on most of the 34 ISIS instrum ents. It has been reliable but we are now finding limitations to what can be achieved with the system. This system also has custom parts and is diff icult to procure. STFC ISIS started a project in 2016 to specify a 2nd gen eration of the standard system. The project team have collected requiremen ts from the ISIS instrument scientists that are based on their future expe riment applications. The specification has been listed for competitive ten der and was due to finish in October 2017. This tender focused on selectin g the control technology rather than trying to rigidly define cabling and connector standards. The presentation will look at the areas that the proj ect team have investigated\, some of the details of the specification and what we want to achieve. The outcome of the tender and selected hardware s hould also be decided before DENIM and so this can also be discussed.\n\nh ttps://events01.synchrotron.org.au/event/50/contributions/1103/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1103/ END:VEVENT BEGIN:VEVENT SUMMARY:Current State of Japanese Engineering Diffractometer\, RESA-1 DTSTART;VALUE=DATE-TIME:20171129T045000Z DTEND;VALUE=DATE-TIME:20171129T051000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1102@events01.synchrotron.org.au DESCRIPTION:Speakers: Hiroshi Suzuki (Japan Atomic Energy Agency)\nRESA-1 is an angular-dispersive neutron engineering diffractometer installed in t he JRR-3 guide hall of the Japan Atomic Energy Agency. This is a large-sca led engineering diffractometer\, which can measure the residual stress ins ide materials at centimeter-order depth non-destructively. The gauge volum e is normally defined using the radial collimator and incident cadmium-sli t. Optionally\, the vertical convergent slit\, which can limit the gauge h eight at a measurement position\, can be installed in the incident neutron beam path alternatively to provide a large sample space. RESA-1 has a cry ogenic load frame with the load capacity of 10 kN. The in-situ deformation behaviour can be evaluated by neutron diffraction at 5 K in minimum tempe rature. Furthermore\, the quarter type Eulerian cradle enables us to measu re crystallographic texture of metals. Unfortunately\, JRR-3 has been susp ended since 2011 due to the Great East Japan Earthquake Disaster. Neverthe less\, we are making efforts to upgrade the RESA-1 continuously for future restart. New type Z-stage was lately developed to realize a long travel d istance in vertical within a range of 300 mm. Furthermore\, we have develo ped lately high intensity monochromator system\, an automatic controlled d ouble focusing Si bent perfect crystal monochromator with multiple Si(400) wafers stacked. Recently we have some fatal problems in not only RESA-1 b ut also any other instruments in JRR-3 during long term stop\, aging degra dation of electrical equipment. It is urgent for us to solve these issues since JRR-3 restarts.\n\nhttps://events01.synchrotron.org.au/event/50/cont ributions/1102/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1102/ END:VEVENT BEGIN:VEVENT SUMMARY:Variable collimation snout for Quokka (Small angle instrument) DTSTART;VALUE=DATE-TIME:20171129T062200Z DTEND;VALUE=DATE-TIME:20171129T062800Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1101@events01.synchrotron.org.au DESCRIPTION:Speakers: Merv Perry (ANSTO)\nIn 2007 ACNS (formally known as The Bragg Institute) commissioned its first small angle instrument known a s Quokka.\nQuokka has a fixed collimation tank of 20meters and a sample a rea gap of 960 mm to allow for a variety of sample environment equipment f rom superconducting magnets to simple 20 position sample changers.\nThe ch allenge was to keep the distance from the sample environment equipment to the fixed collimator section to a minimum to minimise air scattering.\nOri ginally this was done by placing fixed lengths of evacuated aluminium tubi ng onto the fixed collimator. Unfortunately this system was time consuming and did not always optimise the gap between the sample environment and fi xed collimator.\nIn 2016 to 2017 the ACNS Scientific Operations group and Quokka’s instrument scientist successfully developed and built a variabl e collimation snout utilising motor driven linear slides and welded bellow s. This new system is totally non-magnetic as a result of the titanium wel ded bellows and has infinite adjustment over a range of 800mm. This allows for the recently installed polarisation system on Quokka to be utilised w ith all available sample environment equipment.\nChanging the length of th e snout went from hours to just a few minutes with a repeatability greater than 0.1mm over the entire length.\n\nhttps://events01.synchrotron.org.au /event/50/contributions/1101/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1101/ END:VEVENT BEGIN:VEVENT SUMMARY:Update of the transfer of the BioRef (SPATZ) Reflectometer from HZ B to ANSTO DTSTART;VALUE=DATE-TIME:20171129T061600Z DTEND;VALUE=DATE-TIME:20171129T062200Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1100@events01.synchrotron.org.au DESCRIPTION:Speakers: Stewart Pullen (ANSTO)\nThis poster will outline the progress to date on the transfer of the BioRef (SPATZ) reflectometer from the Helmholtz-Zentrum Berlin to ANSTO.

The design of the factory acceptance tests (FAT) and methods of encoding and verification are essential to the operational excellence of slit syst ems. While simple in concept\, the reliable operation of neutron beam slit s can be the cause of several issues including lost position and drift ove r time during use. The independent confirmation of operational requirement s at the FAT can be employed to check performance against the specificatio n\, to confirm that the encoding technique employed is fit for purpose\, a nd to assess reliability and endurance. In this talk several aspects of sl it assembly design and specification will be explored and options for FAT endurance\, repeatability and accuracy testing will be discussed for neutr on beam slit assemblies.\n\nhttps://events01.synchrotron.org.au/event/50/c ontributions/1099/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1099/ END:VEVENT BEGIN:VEVENT SUMMARY:Safety Interlock System and User Interfaces DTSTART;VALUE=DATE-TIME:20171129T060400Z DTEND;VALUE=DATE-TIME:20171129T061000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1098@events01.synchrotron.org.au DESCRIPTION:Speakers: David Federici (Electrical controls Technician)\nSaf ety Interlock System and User Interfaces\nMy poster will be on the safety interlock system (SIS) employed at the ACNS\, focusing on the interfaces i ncluding the touch screens we use to operate the safety system for an inst rument. \nThe touch screen interface design satisfies the needs of various users: \n1. Instrument users require very clear and basic instructions to operate the instrument. A user is brought on sight for only a couple o f days and shown by the instrument scientist how to operate the instrument only once. So the touch screens need to be straight forward and fairly in tuitive to make this possible.\n\n2. Instrument scientists employ the t ouch screen to operate the instrument and analyse faults when the safety s ystem has a safety trip for example due to an emergency stop button being pressed or a safety malfunction occurring. The instrument scientist is the first point of call in any operational error and they decide who needs to be called. For example if there is a master reset required the instrument scientist will call a source officer. \n\n3. The technical staff that employ the touch screen for trouble shooting the safety system in case the re is an error that the instrument scientist can’t recover from. The eve nt log on the touch screen is a convenient central location that technical staff can sight and make a rapid determination of triage requirements.\n\ nhttps://events01.synchrotron.org.au/event/50/contributions/1098/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1098/ END:VEVENT BEGIN:VEVENT SUMMARY:Mechanical testing of the RAMPA Type B Inserts when used in Pb99.9 4cU Lead shielding DTSTART;VALUE=DATE-TIME:20171129T054800Z DTEND;VALUE=DATE-TIME:20171129T060400Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1097@events01.synchrotron.org.au DESCRIPTION:Speakers: Stewart Pullen (ANSTO)\nAs part of the transfer of t he BioRef instrument from Helmholtz Zentrum Berlin (HZB) to ANSTO\, Sydney \, a number of lead shielding components will need to be lifted in and out of their positions. These lifts utilise RAMPA Type B inserts embedded in the lead shielding via a self-tapping process with a pilot hole. These ins erts have been used extensively at other facilities and there is data on t he use of RAMPA Type A inserts in PbSb4 see Ofner (2015). Data on load lim its for inserts when used in Pb99.94Cu lead alloy are not readily availabl e. In order to fulfill the requirements of the Lifting Equipment Approval process at ANSTO a safe load limit needs to be determined prior to utilisa tion at ANSTO.\n\nThe process to determine that safe load limit made use o f a number of mechanical analytical tools including Pull-out testing\, fat igue testing\, and creep testing\; along with tensile testing and XRF Spec troscopy for material characterisation. The results of this testing and th e resulting safe load limit applied to these lift points will be presented .\n\nhttps://events01.synchrotron.org.au/event/50/contributions/1097/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1097/ END:VEVENT BEGIN:VEVENT SUMMARY:Recent enhancements and performance gains from upgrades to ANSTO ’s thermal neutron instrument TAIPAN and the triple-axis and Be-filter s pectrometers DTSTART;VALUE=DATE-TIME:20171129T001000Z DTEND;VALUE=DATE-TIME:20171129T003000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1096@events01.synchrotron.org.au DESCRIPTION:Speakers: Kirrily Rule (ANSTO)\nTAIPAN is the thermal-neutron spectrometer located at the reactor face of Australia’s OPAL reactor (AN STO). TAIPAN hosts two interchangeable secondary instruments\; the triple -axis spectrometer (TAS) and the beryllium-filter spectrometer. The TAS o ption has been operating since 2010 whilst the Be-filter only began operat ing in 2015. TAIPAN is renowned for its versatility and high neutron flux which has allowed the TAS to measure a broad range of samples including s ingle crystals\, powders\, thin films\, and co-aligned multi-crystal array s. While the TAS option is used mostly to study structural and magnetic e xcitations in materials\, the Be-filter option is used to measure vibratio nal density of states from powder samples.\nTAIPAN has recently undergone some upgrades to improve the accessible momentum and energy range of both the TAS and the Be-filter spectrometers. Four key features have been mod ified to improve performance: the accessible momentum transfer has been in creased by re-designing the enclosure\; a sapphire-filter translation-stag e mechanism has been installed to allow epithermal neutrons to pass to the monochromators\; a new Cu-200 double-focussing monochromator has been ins talled to allow monochromatic scattering of neutrons up to 180 meV\; and f inally a new tertiary shutter and snout have been designed to improve the signal-to-noise ratio and reduced background outside the instrument enclos ure. Extensive testing and alignment of all new motion stages were undert aken with reproducibility within ±0.05degrees or ±0.25mm obtained for bo th the monochromator rotation angle & sapphire-filter alignment.\n\nhttps: //events01.synchrotron.org.au/event/50/contributions/1096/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1096/ END:VEVENT BEGIN:VEVENT SUMMARY:Status of Neutron Scattering Facilities at HANARO DTSTART;VALUE=DATE-TIME:20171201T030000Z DTEND;VALUE=DATE-TIME:20171201T032000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1095@events01.synchrotron.org.au DESCRIPTION:Speakers: BAEK SEOK Seong (KAERI)\nHANARO (30MW) is a powerful neutron source with a liquid hydrogen cold source.

It is l ocated at the Science and Technology Facilities Council’s ISIS Neutron a nd Muon Source. The special features of the instrument will be energy-sele ctive neutron imaging and the combination of neutron imaging and neutron d iffraction.\n\nThe instrument is being built in several stages. The first stage is almost complete with two imaging cameras available: a gated CCD c amera and a time-of-flight capable high resolution pixel detector.\n \nCur rently IMAT has a new diffraction detector array in the prototype stage. T he angular coverage of the detectors is 53° vertical and 30° horizontal and the theoretical detecting surface lies on a 2000 mm spherical radius. \n\nThe aim of this design is to reduce the time-of-flight approximation\, usually introduced when using arrays of flat detectors\, by creating curv ed detector elements. In order to follow the curvature\, every single 64-p ixels submodule has been 3D printed.\n\nWe have developed a WLSF scintilla tor detector with a 0.1 m${^2}$ detecting area per module. Each module has 64 × 8 pixels and a 2 mm × 100 mm pixel size. A ZnS/${^6}$LiF scintilla tor combined with a fibre encoding scheme is used to record the neutron ev ents.\n\nhttps://events01.synchrotron.org.au/event/50/contributions/1091/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1091/ END:VEVENT BEGIN:VEVENT SUMMARY:Redesign of Monochromator Shielding of Cold Neutron Triple-Axis Sp ectrometer at HANARO DTSTART;VALUE=DATE-TIME:20171201T010000Z DTEND;VALUE=DATE-TIME:20171201T012000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1090@events01.synchrotron.org.au DESCRIPTION:Speakers: Ji-Myung Ryu (Korea atomic energy research institute )\nA Cold Neutron Triple-Axis Spectrometer (Cold-TAS) was initially instal led in the guide hall of HANARO’s cold neutron research facility in 2012 . Owing to frequent mechanical troubles\, simplification of the sample tab le and the analyzer took place in 2013. And the instrument was licensed fo r normal operation in 2014. Soon after\, however\, HANARO was shut down be cause of the reinforcement activity of the outer walls of the reactor buil ding to enhance the seismic stability. Taking this opportunity\, we decide d to redesign and reconstruct the monochromator shielding of the Cold-TAS because serious deformations were found in it in 2015. The entire shieldin g structure was redesigned to stack horizontally to support the larger wei ght with little deformation. During the redesign process\, we evaluated th e shielding performance for radiation using MCNP. Shielding blocks were fi lled with mixed concrete with lead balls and boron powder. The concrete ha d different densities depending on their strategic location in the shieldi ng structure. To fasten the bottom shielding block with bolts\, stainless steel plates with tapped holes were installed on the concrete floor. After the installation of the redesigned shielding\, we polished the surface of the dance floor to ensure smooth operation of the sample and the analyzer tables. All of the above activities were finished by the end of 2016. Now the instrument control system is under stress testing because it has not been used for a long time. Once the reactor resumes operation\, we will me asure the performance of the redesigned shielding.\n\nhttps://events01.syn chrotron.org.au/event/50/contributions/1090/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1090/ END:VEVENT BEGIN:VEVENT SUMMARY:Spallation Neutron Source Second Target Station Conceptual Design DTSTART;VALUE=DATE-TIME:20171130T222000Z DTEND;VALUE=DATE-TIME:20171130T224000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1089@events01.synchrotron.org.au DESCRIPTION:Speakers: Van Graves (Oak Ridge National Laboratory)\nThe Spal lation Neutron Source is planning a facility upgrade which is split into t wo elements: an accelerator power upgrade and a second target station.

The High Brilliance neu tron Source (HBS)\, currently under development at Forschungszentrum Jüli ch\, will use protons or deuterons from an accelerator in the 10 MeV to 50 MeV range\, shot on a low Z-material in order to produce neutrons. The HB S is optimized to be highly cost efficient and scalable. Medium flux devic es\, which are affordable for universities or companies will be available\ , as well as high flux facilities\, comparable to today’s research react ors.\n\n\nThe heart of the system is the target assembly\, where nuclear r eactions between ions and target nuclei take place to produce neutrons and where the major fraction of the projectiles kinetic energy is converted t o heat. The neutron yield is strongly correlated to the beam power\, makin g the thermomechanical properties of the target material a limiting factor . The ion range\, which is a function of the ion's initial energy\, is lim iting the allowable thickness of target materials with low diffusion coef ficients like beryllium\, due to ion implantation causing severe degaradat ion by blistering. \nFor an efficient high power target with an acceptable lifetime\, smart choice of design parameters is therefore crucial. \n\n\n Simulations show the feasibility of a $10$ kW peak power target producing $10^{13}$ n/s at \n$4\\ \\%$ duty cycle\, for a system on university scale . Latest target design considerations and techniques for effective heat di ssipation will be presented\, which allow the maximization of the neutron yield.\n\nhttps://events01.synchrotron.org.au/event/50/contributions/1088/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1088/ END:VEVENT BEGIN:VEVENT SUMMARY:ESS Instrument Controls DTSTART;VALUE=DATE-TIME:20171129T072200Z DTEND;VALUE=DATE-TIME:20171129T072800Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1087@events01.synchrotron.org.au DESCRIPTION:Speakers: David Brodrick (European Spallation Source ERIC)\nTh e European Spallation Source ERIC (ESS) are actively developing fifteen ne utron instruments\, the first of which will be ready for routine user oper ation by 2023.

Therefore the flight path of the neutrons before and after the sample s hould be not in air but in vacuum or in an atmosphere like Ar or He. \nBec ause Ar is not cheap the goal is to run as long as possible with the filli ng a permissible box. Therefore after the initial Ar filling the Oxygen le vel is logged. As long it is below a certain threshold (e.g. 4.2%) no acti on is done. Above the threshold the box is filled with Ar by cycling with a slight overpressure.

This method allows scientists to see and gauge exactly whether the ideal angle s and positions of the sample can be accessed by a neutron beam. \n\nOur t eam implemented this method for the first time recently\, and this poster will show the design and setup of all lasers\, explain how they work\, and discuss plans for future improvement.\n\nhttps://events01.synchrotron.org .au/event/50/contributions/1074/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1074/ END:VEVENT BEGIN:VEVENT SUMMARY:Systems Engineering Analysis of the Science Productivity Program f or Instrument Improvement Projects DTSTART;VALUE=DATE-TIME:20171128T235000Z DTEND;VALUE=DATE-TIME:20171129T001000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1073@events01.synchrotron.org.au DESCRIPTION:Speakers: Lacy Jones (ORNL Neutron Sciences Directorate)\nThe large-scale investment program Science Productivity is a vehicle by which to prioritize\, stage\, plan and implement requests for directorate fundin g and resource allocations as Instrument Improvement Projects (IIP) to mai ntain and improve neutron instrumentation at the neutron facillities at Oa k Ridge National Laboratory (ORNL)\, Spallation Neutron Source (SNS) and H igh Flux Isotope Reactor (HFIR).

Fifteen instrument proposals have been selected and all of these require a new generation of detectors in order to meet the unprecedented neutron instantaneous flux. Due to the shortage of 3He gas and its counting rate capability limitations\, the detectors of about half of these fifteen instruments will require to be based on a new technology. One of the best alternatives found for neutron detectors is 1 0B. The technology for these is being developed within the Detector Group. The fact that the neutron conversion occurs in a solid layer and that lay ers must be carefully arranged to meet detection requirements\, require no vel engineering solutions. In this presentation\, we will show the mechani cal engineering effort currently underway to implement the 10B technology neutron detectors\, design and construction of prototypes this far\, toget her with the progress and results on these detector demonstrators.

\nShear rheology is a widely used technique in both research and industry for different kinds of materials\, covering various applications. Nevertheless\, hardly any practical system is available whic h is suitable to study low temperature behavior in situ using small angle neutron scattering experiments.\n\nOur approach bases on vertical sandwic h shear geometry\, which allows examining rubber-like or soft matter sampl es.\nThe system is designed to reach high shearing rates while keeping the movement precision around 1μm. To obtain a maximum shearing force up to 300N a massive design was chosen.\nA temperature range between -100 and +1 00 degree celsius was realized using a nitrogen gas flow based temperature control system. \nIn this talk we will show the development from the firs t design stage to the deployable machine and illustrate the problems we fa ced within the implementation of the system.\n\nhttps://events01.synchrotr on.org.au/event/50/contributions/1066/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1066/ END:VEVENT BEGIN:VEVENT SUMMARY:Fan chopper for chopper spectrometers at long pulse neutron source s DTSTART;VALUE=DATE-TIME:20171130T224000Z DTEND;VALUE=DATE-TIME:20171130T230000Z DTSTAMP;VALUE=DATE-TIME:20260615T083544Z UID:indico-contribution-50-1065@events01.synchrotron.org.au DESCRIPTION:Speakers: Peter Harbott (Forschungszentrum Jülich GmbH - JCNS )\nThe unique conditions of the long pulses generated at the European Spal lation Source (ESS) allow for multi-chromatic operation of spectrometers. The full wavelength spectrum of a single ESS pulse is subdivided into a nu mber of sub-pulses of different wavelengths by the chopper system. However \, the chopper system must not only assign a unique wavelength to the sub- pulse but also adapt the time frame to the respective energy of the pulse. A newly developed so called fan chopper is able to selectively suppress s ub-pulses as they are generated by the pulse chopper of the instrument.\nT he design consists of 10 separate blades spinning synchronized to the sour ce frequency of 14 Hz on a common axis like clock hands. Like in a clock t he blades are mounted on hollow shafts. Each of them is connected to an in dividual drive. This setup allows to adjust an angular phase shift between the blades during operation generating an adjustable “slit-pattern”. A first prototype has been built and a feasibility study has been performe d at ISIS on the cold neutron chopper spectrometer LET.

Digital neutron radiog raphy commenced in 1996 and a 3D tomography capability was installed in 20 03. Major deficiencies regarding corrosion of water cooling pipes of the i nternal collimator as well as shielding and control infrastructure were id entified to be addressed in the design of new state-of-the-art neutron rad iography instrument.\n\nA bismuth filter that limited the utilisation of t he beam port is being replaced by a multiple filter exchange unit allowing for radiography using either fast or thermal neutrons or the gamma-ray co mponent of the beam. Due to the optimization of the neutron optics\, the f ield of view on the detector plane was improved from 5x5 cm2 to 35x35 cm2. The highest neutron flux anticipated will increase from 1x107 to 1x109 n. cm-2.sec-1. Shielding design was improved to allow 3 to 8x5x2 m3 and is li ned with a 200 mm thick layer of B-PE.

Persistent hot spots on detectors? In creased radiation levels? These are common aspects of a new instrument\, a nd even an old instrument. The divergent beam exiting from a guide\, or re flecting from a chopper\, can create unwanted background\, or damage neigh bouring equipment.\nFor instance\, persistent hot spots and higher backgro und counts on the detector of the backscattering spectrometer\, EMU\, had been present since hot commissioning. While the scientists and technical s upport team worked on step-wise tests to localise some of the causes\, the extreme worst-case beam divergence was also investigated within the CAD m odel. This additional CAD analysis showed that a neutron beam exiting a gu ide with the highest possible beam divergence could actually bypass the in -operation beam stop and reflect off an analyser array back onto the detec tors. This was just one of a few issues creating a higher background for t he instrument.\nFrom our experience\, during the instrument commissioning stage and subsequent years after\, instrument and technical support teams spend a lot of time adding and improving shielding\, to reduce background neutrons and gammas. This tedious and time consuming process may be reduce d if future design projects allow for specific\, divergent neutron beams\, milestone design review steps. Divergent beams and their shielding are ve ry easily overlooked in the design phase of instrument projects. We will o utline a mechanism allowing to avoid such problems\, through consideration throughout the design process.\n\nhttps://events01.synchrotron.org.au/eve nt/50/contributions/1058/ LOCATION: URL:https://events01.synchrotron.org.au/event/50/contributions/1058/ END:VEVENT END:VCALENDAR
